Will current flow more easily through a th ick wire or a thin wire of the same material, when connected to the same source? Why?
Resistance
of a wire,
Where,
=
Resistivity of the material of the wire
l = Length of the wire
A = Area of cross-section of the wire
Resistance is inversely proportional to the area of cross-section of the wire.
Thicker the wire, lower is the resistance of the wire and vice-versa. Therefore, current can flow more easily through a thick wire than a thin wire.
